I've read posts online by people who don't like you or who say you shouldn't be taken seriously.

I'm not surprised. Why would you take them seriously? One of my favorite critics is a particularly sad, anonymous devotee of the S.C.A.R.S. combat system who seems to have profoundly low self-esteem. A few others include people whose systems I've publicly panned, like the "Hikuta" practitioners, as well as various brittle ninja and other pretenders. Every time someone like that criticizes me online, I know I'm doing something right – because anyone who would side with these kung-fools is going to get what he deserves, ultimately.
